That is quite true, its is probably very difficult for a single person in Italy to go live on their own due to house prices. But as a culture, Italians might also not feel any need to leave home as soon as other people.

I live in a neighboring country, Malta, and we share some similarities. Because our country are two small islands, housing is very expensive. So we have a unique case where a lot of people live with their parents until they get married or are in a very very stable relationship/financially well. This makes us very dependant on our parents, but it is not as bad as people make it seem. Our parents can depend on us to help and we continue saving.

There isin't a lot that can be done. Moving to one of the Northern European countries will not solve the problems our Southern countries are having.
